Welll..... I can't agree with you on that. There are lawyers and then there are lawyers. Most lawyers are actually good, honest folks whose professional training is a positive asset in crafting solid legislation, and also in understanding the legal ramifications of the activities over which Congress has legitimate oversight. Those sorts of folks are good to have around.
Unfortunately, there is also that class of lawyers who have figured out how to make a good living by finding the cracks and gaps in the law.... and those are the ones who tend to be attracted to Congressional careers; and who (I agree) need to be cast into the outer darkness.
As to needing more engineers in Congress .... well, speaking as an engineer, I'd have to say that's not a good plan. In my experience, engineers tend to be folks who are comfortable with things that behave predictably, and that can be arranged as necessary to accomplish a specific task.
For the same reason, engineers tend to be incredibly naive about the interpersonal dynamics that govern actual politics; people just don't work that way.
Your description of our fellow engineers portrays folks who possess what is sorely lacking in government today: COMMON SENSE.
I’ll trade doctors or engineers who might lack some of that information about personal relationships (and ain’t it working grand so far) but who possess that common sense for every one of those Machiavellian scumbag lawyers now legislating America out of existance.
And as for having a few “twisters” around to “craft legislation,” they’re up there already. They’re called STAFFERS and, if they screw up or try to “craft” legislation that runs longer than 10 pages — DOUBLE SPACED — and only they can understand, THEY CAN BE FIRED!!!
